Abstract
Official abstract text for this publication.
In a lining material peeling method of peeling a lining material, which is fixedly formed on a surface of a base material, from the base material, a liquefied fluid which evaporates after injection is injected to a boundary between the base material and the lining material.
First claim
Opening claim text (preview).
What is claimed is: 1. A lining material peeling method of peeling a lining material, which is fixedly formed on a surface of a base material, from the base material, wherein a liquefied fluid which evaporates after injection is injected to a boundary between the base material and the lining material by a nozzle unit in a state in which a distal end portion of the nozzle unit penetrates the lining material. 2. The lining material peeling method according to claim 1 , wherein the liquefied fluid is injected onto a surface of the lining material to form a penetration hole in the lining material, and the liquefied fluid is injected from the penetration hole to the boundary between the base material and the lining material. 3. The lining material peeling method according to claim 1 , wherein the nozzle unit includes a tubular portion in which a flow path configured to guide the liquefied fluid is formed and which has an injection opening formed at the distal end portion of the nozzle unit. 4. The lining material peeling method according to claim 3 , wherein the distal end portion of the nozzle unit of the tubular portion is bent or curved and connected to a base portion, and the flow path is formed in a part including the distal end portion of the nozzle unit and the base portion. 5. The lining material peeling method according to claim 4 , wherein, in a state in which the distal end portion of the nozzle unit penetrates the lining material, the liquefied fluid is injected to the boundary between the base material and the lining material by tilting the tubular portion with respect to the surface of the lining material and by rotating the tubular portion about an axis of the base portion. 6. The lining material peeling method according to claim 1 , wherein the base material is a concrete material, and the lining material is a polyurea material. 7. The lining material peeling method according to claim 1 , wherein the base material is a metal pipe, and the lining material is a fiber-reinforced plastic material. 8. The lining material peeling method according to claim 1 , wherein the liquefied fluid is liquid nitrogen.
